E_pois_noinfl

Computes the expected value from a Poisson (PP) distribution based on the model parameters and covariates.

internal

Estimates one-inflated positive Poisson (OIPP) and
one-inflated zero-truncated negative binomial (OIZTNB) regression
models. A suite of ancillary statistical tools are also provided,
including: estimation of positive Poisson (PP) and zero-truncated
negative binomial (ZTNB) models; marginal effects and their standard
errors; diagnostic likelihood ratio and Wald tests; plotting;
predicted counts and expected responses; and random variate
generation. The models and tools, as well as four applications, are
shown in Godwin, R. T. (2024). "One-inflated zero-truncated count
regression models" arXiv preprint <doi:10.48550/arXiv.2402.02272>.
